NINA & FREDERIK - French song identification on Youtube

Hi,
Does anyone recognize the French song that Nina & Frederik sing in the beginning of the following videoclip on Youtube: Nina & Frederik (songs from 'Verdens rigeste pige'1958).
The song can be heard from 0:00 - 1:10. I will appreciate very much info of the title, and also the lyrics translated into English.
Thanks a lot.

don't know what song it is but here is the english translation

l'hiver était froid=winter was cold
aussi froid que ton ame=as cold as u're soul
et pourtant je l'aimais= but i loved him

ton amour était fou=u're love was crazy
aussi fou que ton coeur=as crazy as u're heart
et pourtant je t'aimais=but i loved you

Thank you so very much - highly appreciated.

u welcome!
